Abstract
A polyester resin comprises 35 to 90 mole
percent of the unit (I), 0.5 to 4 mole percent of
the unit (II), 0.5 to 30 mole percent of the unit
(III) and 0.5 to 30 mole percent of the unit (IV),
exhibiting the anisotropy in its molten state. The
polyestercomposition comprises the polyester resin
as defined above and up to 95 per cent by weight of
an inorganic filler.
